Titan Black (Kepler) vs GTX 980 (Maxwell) CUDA core power?

Hello everyone,

I'm a video editor working in Premiere Pro CC and so CUDA matters for me. Basically I've seen a Kepler Titan Black for £400 - it has 2880 cores, the Maxwell 980 however, has 2048.

Whilst I understand the Titan Black has 6GB RAM opposed to the 980's 4GB and more CUDA cores, I've read that the Maxwell CUDA cores actually perform 40% faster than the Kepler architecture. So, as far as I understand you can't count CUDA for CUDA cores. What I want to know, is whether this means the 980 will be better for my rendering/CUDA performance despite having less cores (given that they're meant to have higher performance per each core apparently)?

The link about the 40% more performance is here:

If you load uses 64-bit floating point calculations the Titan Black will be much faster than any Maxwell card, because Maxwell doesn't have the same FP64 hardware. I have no idea if Premiere uses FP64 or not.

Ah man, how on earth would I find out about that? I've been looking and can't find anything!! I know it's a beast of a card regardless, but I figured the new architecture and that link I posted pointed to a lesser card within Maxwell would hold up due to its increased performance per core :S
